Default Ignition Control Module

Hey i was just wondering what would cause a 1351, 1361, and 1371 trouble codes?

Could it be the ignition control module? I have a new delco disributor, so i dont think it's that. The plugs and wires are new. The car is running REALLY rich and i dont think it is running in closed loop fuel injection (p0125). I am also getting MAF codes too, but i have a new MAF (p0100, p0102, p0103).

Any ideas anyone?

could somehting other than a bad opti cause this?

Could it be messy wiring? Im thinking about getting a whole new wiring harness.

What do you think of http://www.speartech.com/customharnessinfo.html ?

My sensors are all fuxed up and i just want a simplified EFI system.

I'd replace the ignition module first, clear the codes and drive it. If you are still throwing opti codes, you need to pull that opti out. Ignition module will only cost you roughly 50 bucks.
